Overview

Explanation

A complication of mitral valve stenosis or mitral valve regurgitation is an arrhythmia that is created from disruption of the web of nerves that relay electrical impulses on the right atrium at the sinoatrial (SA) node. Mitral stenosis weakens communication pathways causing irregular and chaotic firing. Atrial fibrillation is the most common arrhythmia that arises from mitral valve stenosis. Other arrhythmias may occur from prolonged valve damage that may contribute to cardiac hypertrophy and stretching of chambers that may contribute to ventricular hypertension and arrhythmias.
